Long Description:After 80 years of providing factory tours, new OSHA standards and regulations forced the Kelloggs Corporation to close its doors to the public. However, in 1998, Kellogg's opened Cereal City USA adjacent to the factory. At Kellogg's Cereal City, visitors can tour a simulated cereal production line where they will learn how Kellogg’s Corn Flakes are made. (This location is now closed)
